Smart contracts on Ethereum are fully self contained and any information or access to off-chain data is restricted. Tellor solves this problem by creating a system where parties can request the value of an off-chain data point (e.g. ETH/USD) and miners compete to add this value to an on-chain data bank, accessible by all Ethereum smart contracts. Inputs to a data series are secured by a network of staked miners. The main Tellor smart contract creates a time series of each requested data series and aims to become the standard source of high value data for decentralized applications. This oracle, “Tellor”, utilizes similar incentive mechanisms to other cryptocurrency systems through the issuance of Tellor’s token, Tributes, that are used to request a particular data series from miners.
MATRIX AI Network (MAN) is a global open-source, public, intelligent blockchain-based distributed computing platform and operating system that combines artificial intelligence (AI) and blockchain. MATRIX was created to make blockchains faster, more flexible, more secure, and more intelligent. Besides boasting an impressive 50.000 transactions per second, there are a couple of features which makes Matrix AI Network stand out from its competitors. Matrix adopts a Hybrid PoS + PoW consensus mechanism instead of the traditional Hash computations. The mechanism makes use of value-added computation through the use of the Markov Chain Monte Carlo (MCMC) computations. This computation set is to be used as the Proof-of-Work protocol. This allows the mining process to not only generate MAN tokens but to also be used to power real-world applications. Currently being used in collaboration with Beijing cancer Research hospital to improve speed and accuracy of a cancer diagnosis. While the project seems ambitious with the integration of a working AI in so many areas, the AI-part is already done. Matrix now only has to deliver a working blockchain solution. MATRIX will be launching several community activities after its testnet launch, including a Bug Bounty Program and a Dapp competition, as well as introducing the MATRIX Blockchain Browser and Online Wallet Prototype. Details and instructions will be shared over the coming weeks. Full manner is set to launch December 2018. The MATRIX mining machine is set to launch for sale end of the year 2018.
